Improved synthesis of the Ni(ii) complex of the Schiff base of (S)-2-[N-(N′-benzylprolyl)amino]benzophenone and glycine
Abstract
The environmental impact of a known synthesis of the Ni complex of the Schiff base of (S)-2-[N-(N′-benzylprolyl)amino]benzophenone and glycine was decreased by optimisation of the ratio the starting materials; a new starting material, Ni(NO3)2·6NH3, was evaluated as a nickel source.
